decidedly longer than the 2 lower. The corolla expands from 
below the top of the calyx into a very large open throat, and is 
pubescent within. 
There is no close congener known, the genus which I here 
propose being monotypic. The Arizona-Mexican plants referred 
to Cedronella (C. Mexicana (H. B. K.) Benth, C. pallida Lindl., 
C. aurantiaca A. Gray, C. parviflora A. Gray, C. coccinea 
Greene) have no more characters in common with C. cordata than 
has the typical species. They form a natural group, differing 
from both the others in their narrow, tubular corollas, scarcely at 
all ampliate above and by their conspicuously exserted stamens. 
Meehania is dedicated to Thomas Meehan, a life-long student 
of plants and a liberal patron of science, who has contributed im- 
portant and valuable information on systematic and physiological 
botany for a long period of years. 
MeEEnHANIA Britton. 
A low, pubescent, spreading or decumbent herb with long- 
petioled, cordate leaves, trailing, leafy stolons and large, blue 
flowers in terminal, secund, bracted spikes. Calyx campanulate, 
15-nerved, 2-lipped, its teeth all lanceolate, acute, the 3 upper 
longer and slightly narrower than the 2 lower. Corolla much 
exserted, puberulent without, pubescent within, the tube narrow 
at the base, gradually widely ampliate above, the limb 2-lipped ; 
upper lip 2-lobed, arched, about as long as the lower, the lobes 
ovate, obtuse; lower lip spreading, 3-lobed, the middle lobe emar- 
ginate, broader than the lateral ones. Stamens 4, didynamous, 
all antheriferous, ascending under the upper lip, the upper pair 
somewhat longer than the lower. Anthers 2-celled, the sacs’ 
parallel. Ovary deeply 4-parted. Style equally 2-cleft at the
